About cyst excision

One of the most common dermatological procedures is cyst excision.  There are several different types of cysts that can occur on the skin or scalp, with the most common ones being an epidermal inclusion cysts and pilar cysts.  Most cysts are easily removed by your dermatologist.  After prepping the area, your dermatologist will numb the area with an injection of local anesthesia, such as lidocaine with epinephrine.  Your dermatologist will often try to keep the incision small and to “birth” the cyst whole through a small opening.  Sometimes, however, this is not possible.  In which case the material inside the cyst, typically a cheesy foul-smelling substance, will be extruded and then the cyst wall removed.  The cyst wall should be removed in its entirety to reduce the risk of recurrence.  If any cyst material has escaped the cyst, your dermatologist may irrigate the area with sterile saline to clean it and prevent any inflammation from developing to the cyst contents.  After the cyst has been completely removed, any bleeding will be stopped, and the wound evaluated for closure.  Usually cyst excisions are closed easily, but it is important to eliminate any dead space with deep sutures and to close the wound without tension by undermining the adjacent skin.  Depending on the cyst location, you will then return to your dermatologist in 5 days to two weeks for suture removal.
